Overview
The MMBZ5235BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features a nominal Zener voltage of 6.8 V with a tolerance range of 6.46 V to 7.14 V at a test current of 0.25 mA. The device has a maximum power dissipation of 200 mW and a thermal resistance of 625 °C/W. Electrical specifications include a maximum Zener impedance of 5 Ω at the test current and a maximum reverse leakage current of 3.0 μA at 5.0 V. The forward voltage is rated at 0.9 V when tested at 10 mA.
Feature Summary
- Dual isolated Zener diodes integrated into a single ultra-small surface mount package
- Planar die construction designed for automated assembly processes
- Lead-free plating with matte tin finish annealed over Alloy 42 leadframe
Applications
- Voltage reference circuits requiring dual independent channels
- Signal clamping applications in compact electronic designs
- Power supply protection utilizing dual isolation
Procurement Notes
Verify that the ordering suffix matches the required packaging configuration. The standard designation includes the -7-F suffix indicating tape and reel shipping quantities. Confirm RoHS compliance status and date code requirements against specific project constraints before finalizing procurement orders.
Selection Notes
Select this component when dual independent Zener regulation is required within a minimal footprint. The SOT-363 package accommodates two separate devices, reducing board space compared to individual discrete components. Ensure the 6.8 V breakdown voltage aligns with circuit design parameters and verify thermal management capabilities for the intended operating environment.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series covers a wide range of Zener voltages from 2.4 V to 39 V. All variants share identical physical dimensions and electrical testing conditions, differing primarily in their specific breakdown voltage ratings and associated marking codes.
Replacement Considerations
Direct substitutes include other MMBZ5235BS variants from Diodes Incorporated. Cross-manufacturer replacements must match the SOT-363 package outline, 6.8 V nominal voltage, and 200 mW power rating to ensure mechanical and electrical compatibility.
